Incorporating emissions models within a multi-objective vehicle routing problem.

Conference Proceeding
Urquhart, N. B., Scott, C., & Hart, E. (2013)
Incorporating emissions models within a multi-objective vehicle routing problem. In C. Blum (Ed.), GECCO'13 Companion: Proceeding of the fifteenth annual conference companion on Genetic and evolutionary computation, (193-194). https://doi.org/10.1145/2464576.2464663
